According to https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux_for_real_time/7/html/reference_guide/using_mlock_to_avoid_page_io, it looks sufficient to mlock; I checked some information, and some places said that mlock alone cannot guarantee that memory can be locked, because there may be copy-on-write problems. I'm not sure if this is the problem. [refer to this article](https://www.cnblogs.com/lixiaofei1987/p/3205002.html) -- This is an automated message from the Apache Git Service.
